I'm totally new to Stratagus, having just discovered it. I've downloaded Wargus but I can't seem to figure out how to play online with a friend. Can we use the "metaserver" to supply each other's IP addresses and ports?

I've searched for documentation on this but haven't been able to find anything.

Also, over on the steam group I saw a comment about games getting out of sync. Is this a common issue?

I've made a slight bit of progress. I'm using two machines on my local network to test things out. I'm using their local IP addresses to connect (i.e. 192.168.10.100 & 192.168.10.101).

When either machine hosts, it can see the second machine trying to join ("machine2 Preparing"), but the second machine immediately gets a "map not available" error. After that, each time it tries to connect, it times out and says "Cannot reach server."

What I do to play "local" multiplayer is starting one game normally, and then another with the following command line stuff: "-P port". If it still doesn't work for you, I would check if stderr.txt says anything.
